Here's my crush update so far.
Amador (Shake Ridge) Tempranillo .6 TA, 23.5 Brix 3.8 pH (before fermentation/4.1 after (adding tartaric) (all 400lbs red)
Fiddletown (Slate Creek) Malbec .57 TA, 24 Brix 3.9 pH (adding tartaric) (starting ferment 266 lbs red/133 lbs rose))
Amador (Shake Ridge) Barbera .8 TA, 25 Brix 3.2 pH (done ferment 266 lbs red/133 lbs rose)
Amador (Shake Ridge) Viognier .6 TA, 25 Brix 3.6 pH (adding tartaric) (almost done ferment, 400 dry white)
Fiddletown (Slate Creek) Cab Franc .6 TA, 25 Brix 3.6 pH (just starting ferment 400lbs dry red)
Saturday I'm picking up 400lbs Zinfandel and 400lbs Mourvedre both at Shake Ridge Ranch in Amador (it's about a mile from my house).
This is my first time making wine in California. All the varietals except Cab. Franc are new to me. The Franc I got from Slate Creek was beautiful (they are down the world's worst dirt road from my house...). The smell reminded me of wine making in the Finger Lakes with the wonderful aroma of freshly picked Franc -it's almost like cut cedar trees or black pepper -not like a grape smell at all. The Malbec was totally new to be so everything was discovery. The folks I bought them from were downplaying the Franc and talking all about the Malbec. These grapes seemed totally neutral to me, and other than being very dark and juicy (that's why I used a bunch in a rosé) I didn't get it. Once they started fermenting I got it -they really filled the room with blackberries and flowers -really amazing! If I can capture just a bit of these amazing smells in the final wine I'll be happy. BTW, I understand now why the Malbec family is referred to as "Fer" ("Iron") in France. I have a nice manual crusher/stemmer and I thought "why would anyone need a motorized one?" until I had to process the Malbec -iron indeed...
Tempranillo is a learning experience too. It never really had any interesting aromas, either as grapes or in fermentation. What it has in spades is tannin -wow! I can see why so many blends are based on this grape. On it's own it could be over-powering and under-whelming, but it has such structure and backbone that it will make for a great core to a blend for long aging. The winery that runs the vineyard (Yorba) doesn't generally release their Tempranillo for 8 years or so, and I can see why (don't think I will have that kind of patience).
My favorite so far has been Barbera. The winegrower contacted me last weekend with the option of getting it when it was "bright crunchy and juicy" or wait until the acids died down a bit more. Very glad I opted for the earlier harvest -the grapes were beautiful and such a deep bright purple and zippy taste. Even punching down the cap the grapes seemed to be bursting with energy. I'm having a glass of rose that I pulled for testing and it's already tasting pretty good, for a 1 week old wine. The rest is broken into two separate cuvées, one as an early maturing, Italian style old school red with no MLF and a yeast to enhance the fruit. The other is being fermented with a yeast to accentuate the body and mouthfeel and destined to add life and color to my other blends.
Oh, long message -shutting up now...
